It might be hard to imagine being worth £81 million at the age of 18, but for football's wonderkids, the figure isn't out of reach.

A leading research group in Switzerland has put together a list of estimated transfer values for the most expensive footballers in Europe — and we've singled out the highest-ranking teenagers.

5. Gianluigi Donnarumma, AC Milan — €39 million (£34.1 million).

Italian goalkeeper Gianluigi Donnarumma's talents belie his years. The 18-year-old may lack experience but he is already a first team staple at AC Milan.

Last season he made an astonishing 158 saves from 41 appearances in all competitions and clearly has a promising future in football.

That future is currently up in the air, though. This is because Donnarumma has reportedly rejected an £80,000 per week contract to stay at Milan, meaning he could be on the move in the summer transfer window.

4. Renato Sanches, FC Bayern München — €45.4 million (£39.7 million).

Renato Sanches became a league champion with Benfica when he was just 18 years old, in 2016. Later that summer he helped Portugal win the European Championships and then secured a mega money move to FC Bayern München.

Sanches has attracted comparisons to legendary Dutchman Edgar Davids, not just because of his hairstyle, but also his playing style. A defensive midfielder by trade, Sanches — now 19 — is yet to break into the Bayern first team, but it is surely only a matter of time before he ousts the likes of Arturo Vidal.
